i RESILIENT WHEEL.

Specification of Letters Patent. Patented Sept. 10, 1912. Application med october 4, 1911. serial No. 652,865.l

yBexar and State ofl Texas, have invented certain new 'and useful Improvements in a specification. Y

ThisA invention relates to resilient wheels, and has for itsv4 object the provision of an improved device of this character constructed in such manner as to present a nonpuncturable surface tothe road bed, while at the same time being capable of absorbing the shocks and jars incident to 4the passage of the vehicle over such road bed. A

Further objects and advantages of the invention will beset fforth in the detailed description which now follows.

In the accompanyingdrawing, Figure 1 is a view partly in side elevation and partly in section'of a wheel constructed in accordance with theinvention, Fig. 2 1s a view .partly in edge elevation and partly in' section, Fig. 3 .is a sectional view through one of the spokes, and Fig. 4 is a sectional view through the rim and tire. j

' Like numerals 'designate corresponding parts in all the figures ofthe drawing.

Referring to the drawing, the numeral 5 designatesa hub havinT an integral flange 6 and a movable ange bolts 8 serving to draw these flanges together, and to clamp' between them a filling piece 9. Metal disks 10 have their inner edges clamped between the flanges and the filling piece. An inner ring 11 and an outer ring 12 are located between the disks 10. The outer ring carries transverse lu s '13 which pass through openings 14 in t e disks. Bolts 15 pass through the disks and draw said disks toward each other., this action holding the `disks rmly uponthe lugs 13. The spokes -comprise the sleeves 16, having flanges 17 at their outer ends which limit the inward movement of the sleeves through the ring 12. The angular heads (see Figs. 1 and 3) 4of plugs 18 pass through the inner rim.

Plugs 18 are threaded into the inner ends .of the sleeves 16. Sprin S19 and 20 bear between the outer ends o the plugs 18 and .the outer ends of tubular push rods 21.

These push rodsvcarry rollers 22 at theirouter lends; These rollers travel in a chann el 23 of arim portion 211. -The rim conslsts of portion 24, a wooden portion 25 and an outer channelfportion 26 formed to receive a preferably solid rubber tire 27. The outer spring 19, which I term a compression spring, is` compressed when put -in the wheel, and. its function is to maintain a definite pressure on the rim at allpoin'ts Al and to cause the rim to occupy a position concentric with the hub when all load is relieved. These springs -also lielp to carry the load whenfurther compressed. There fore, when the wheel is subjected to the load these springs keep the rim at a distance from the hub of the wheel in proportion to the degree that they are compressed.

The plugs 18 provide an.airtight closure tends to resist any sudden movement of the` push rods and will act as a shock absorber and safety device. The roller and continuous' channel structure shown in Fig. 1 at 23 and 24 permits relative vertical movement between the hub and rim. portions, while always maintaining the requisite bearing between these parts. Furthermore, the provision of the disks entirely -inclosing the spokes keeps out dust, mud, and other dirt, and atthe same time vprovides the necessary strength to enable the wheel to withstand the enormous lateral pressure-to which it is subjected in going around curves. While the elements h erein shown and described are well adapted to serve the pur? poses for whichthey are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes vwithin its purview such changes as may be made within the scope of the lappended claims.

Having described my inventionfwhat I claim is: A

1. A wheel 'of the character described, comprising a hub portion, a pair of metallic disks carried by said hub ortion, an inner ring and an outer ring said disks, sleeves carried by said rings, tu-

bular push rods slidably. engaged in said sleeves, rollers carried by the outer ends of said push rods, springs disposed within said isposed between push rocls for resisting ille movement of the push. roa'ls int-o Suid sleeve, und a rim, coinprising a channel member in which Suid rollers engage.

2. ln e Wheel of lhe character described, the eoinbinzilien with a hub .and :L rim, the interior fue@ of sziicl rim being' einil'inuously eli: nnelecl, of a pair of metallic (lieke fixed to the hub und of Such clinnxel'er lo eX- fenfl lo and lie upon each sifle of the rim, the eurer portions of said (links Sliding; over ehe outer faces oi and rim, n pair of eoneenlrie rings loeuled between said disks, one or' said ringe` verse lugs formeel thereon which Dees through openings in the disks, a plurality having' u plurality of trains sind plugs passing through the inner ring,

tubular pufili rods slidably mount-ed inthe sleees, spring; bearing between said tubulnr pushrods unclsnicl plug, androll'ers Carried by traveling` in lhe Channel oi2 the rim. In testimony whereof I aflix my signatl'lre in prefrenc-e of two wiinesses.
